Hi everybody , I'm new for the gnuradio.Now my researching is about
digital beacon receiver.So what's my problem is in the list below
1. How do everybody set MUX? I tried to read the datasheet but It
wasn't make sense for me.So what I do is use the GRC and used the Usrp
block so i know that my db BasicRx is on side B RXA and My WBX is on
Side A Rx2 but if i want to set mux in the python program how do i do?

2. I tried to find the signal's phase,so i generated the signal
about 1.5M from signal generator (just for test) directly to the Basic
Rx Db. So what i expect is the IQ signal that show in the GRC Scope sink
would be the constant(cosphi and sinphi) signal but It's not ,the
signal seem to be like the cycle(period). What do I misunderstanding?

3. From the Question 2. How can I find the phase of the signal that i generate through the usrp.
